The Ideal LED Task Light is Now in Reach. Astra shines brightly with a pleasing, warm white light. Its minimal 6 watt power use will lighten your energy load for years to come. And naturally, its low energy use contributes to LEED credits. With five points of adjustment, Astra goes the distance in ergonomic task lighting. Astra is designed to fit your workspace - whether mounted to a Sierra toolbar, the edge of your worksurface or attached to a panel system. So even when your projects get out of hand, the Astra is never out of reach.
